toad安裝oracle客戶端過程

一、描述

使用toad連接oracle時提示找不到客戶端，下面分享一下處理過程

二、過程

1、到ORACLE 網站下載instantclient客戶端

https://www.oracle.com/database/technologies/instant-client/winx64-64-downloads.html

2、Oracle Instatnt Client解壓至指定目錄（自定義）如本例中放到如下目錄 

D:\program\instantclient_18_5

3、配置系統變量

NLS_LANG = AMERICAN_AMERICA.ZHS16GBK
TNS_ADMIN = D:\program\instantclient_18_5\
LD_LIBRARY_PATH = D:\program\instantclient_18_5
SQLPATH = D:\program\instantclient_18_5
ORACLE_HOME = D:\program\instantclient_18_5
Path（在變量中加入） D:\program\instantclient_18_5

5、添加配置文件sqlnet.ora和tnsnames.ora

sqlnet.ora代碼如下：

# sqlnet.ora Network Configuration File: /u01/app/oracle/product/11.2.0/db_1/network/admin/sqlnet.ora
# Generated by Oracle configuration tools.

NAMES.DIRECTORY_PATH= (TNSNAMES, EZCONNECT)

ADR_BASE = D:\program\instantclient_18_5

tnsnames.ora代碼如下：

ORCL =
  (DESCRIPTION =
    (ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.1.233)(PORT = 1521))
    (CONNECT_DATA =
      (SERVER = DEDICATED)
      (SERVICE_NAME = orcl)
    )
  )

6、通過toad連接OK
